Datalink
Product Feature:
- DataLink now offers the DL3500-DH+/IAP
package that significantly reduces your AB Ethernet upgrading costs
as you don't need to replace each DH+ PLC processor/device. Simply make the DL3500-DH+/IAP a node on DH+ and then
interface to your AB Ethernet.
- AB PLC users can interface bi-directionally
between Allen-Bradley Data Highway Plus (DH+)
/ DH-485 and AB Ethernet (CIP & 2222 protocols).
- AB Ethernet (Master) to DH+ is the optimal
communication direction. This allows multiple AB Ethernet (CIP and 2222)
devices to communicate to multiple DH+ nodes using the DataLink DL3500-DH+/IAP.

Solution:
Q:I just bought a new PC and discovered that it has a smaller PCI slot that the 1784-PKTx card doesn't support. Can you help me out?
A: DataLink can provide an external, palm-sized, USB DL3500 controller to solve that problem. Our products are: DL3500-DH+/DF1 and DL3500-DH-485/DF1.
Datalink
Solution:
Q:We are looking for a system to take some downtime information off of several Micrologix PLCs and link them to a SLC 5/04 PLC .
A: We have 2 possible solution for this application:
DL3500-DH+/DF1: This solution will enable the Micrologix via Channel 0 (DF1) to become a node on DH+.
DL7000-ETH/DH+: This solution will allow the Micrologix (AB Ethernet) to access the nodes on DH+.
Datalink

Product Testimonal:
The DL3000-KFX is unbelievable....it keeps on running in the most disgusting, hazardous environment you could ever imagine. We didn't even know what the controller was because of all the messy residue covering the box....it just keeps on working.

Ethernet/IP Background
EtherNet/IP (Ethernet Industrial Protocol) is an open communications protocol developed by Rockwell Automation, managed by ODVA and designed for use in process control and other industrial automation applications. EtherNet/IP can be easily confused as a combination of Ethernet (the physical layer, link, or medium used in most office and many industrial networking environments) and the Internet Protocol, the world’s most ubiquitous (internet) networking protocol and part of the TCP/IP model, comprising a suite of protocols operating at the link, internet (or networking), transport, and application layers.
By comparison, EtherNet/IP is an industrial application layer protocol operating over the Ethernet medium and used for communication between industrial control systems and their components, such as a programmable automation controller, programmable logic controller or an I/O system. Furthermore, the “IP” in EtherNet/IP, is not an abbreviation for “Internet Protocol” but instead stands for “Industrial Protocol”, referring to Rockwell’s adoption of Common Industrial Protocol (CIP) standards as EtherNet/IP was developed.
Confusing matters further is the fact that when using the OSI Reference Model, EtherNet/IP, at the application layer, operates over both Ethernet (at the physical layer) and IP (at the network layer) and thus complements each of these technologies.
History
EtherNet/IP was developed in the late 1990’s by Rockwell Automation as part of Rockwell’s industrial Ethernet networking solutions. With little or no input taken from other ODVA members, Rockwell gave EtherNet/IP its moniker and handed it over to ODVA, which now manages the protocol and assures multivendor system interoperability by requiring adherence to established standards whenever new products that utilize the protocol are developed.
Today, EtherNet/IP is most commonly used in industrial automation settings (e.g., water processing plants, manufacturing facilities, utilities) in the US and Asia for communication to and from Rockwell Automation’s Allen-Bradley-brand control systems. However, other industrial automation and control system vendors, including Opto 22 and WAGO Corporation, have developed programmable automation controllers and I/O capable of communicating via EtherNet/IP.
Schneider-Electric developed an EtherNet/IP cards for both PLC Quantum and Premium on the Unity Platform.
EtherNet/IP classifies Ethernet nodes as predefined device types with specific behaviors. Among other things, this enables:
- Transfer of basic I/O data via UDP-based implicit messaging
- Uploading and downloading of parameters, setpoints, programs and recipes via TCP (i.e., explicit messaging.)
- Polled, cyclic and change-of-state monitoring via UDP, such as RPI and COS in Allen Bradley's ControlLogix control systems.
- One-to-one (unicast), one-to-many (multicast), and one-to-all (broadcast) communication via TCP.
